IGF-1 LR3
Also known as Long R3 IGF-1
A modified form of insulin-like growth factor 1 with a substantially extended half-life.
What it is
An analog of IGF-1, the downstream growth factor produced largely in the liver in response to growth hormone. Structural changes reduce its binding to carrier proteins, which is why it persists longer than native IGF-1.
What the research has examined
Research has examined cell proliferation and muscle tissue signaling in laboratory settings. Because IGF-1 signaling touches growth pathways broadly, it is one of the more cautiously discussed compounds in this group.
